BOBBIN TERMINAL INSERTION MACHINE The present invention relates generally to a terminal insertion machine for inserting a plurality of electrical terminals into a dielectric bobbin for holding the windings of an electric motor. In a specific application for the insertion machine according to the present invention, a bobbin is provided with a brush holder for holding the motor brushes, with the elctrical input and output leads for the motor windings and brushes being terminated to electrical terminals which are inserted into the bobbin by the machine according to the present invention.

During assembly of an electric motor, it is desirable to provide a collar around the motor windings, with the collar further retaining and positioning the motor brushes around the periphery of the rotor. It is also desirable that the collar take the form of a bobbin supplied as a subassembly of a unitary molding of dielectric material provided with metallic electric terminals secured therein to which the input and output leads for the motor windings and brushes are to be terminated during assembly of the electric motor within the bobbin.

It is therefore an object of the present invention to provide a machine for inserting a plurality of electrical terminals within a bobbin for an electric motor subassembly.

An object of the present invention is to provide a machine for serially supplying a plurality of electrical terminals spaced along a common carrier strip, severing individual terminals from the strip, bending the terminals to a desired configuration and subsequently inserting the terminals into a corresponding bobbin for an electric motor and its windings and brushes.

Another object of the present invention is to provide an insertion machine which serially supplies electrical terminals in strip form to a terminal holder portion of an insertion station, with means being provided on the machine for severing the carrier strip from the terminal held in the holder portion, and with a ram for actuating the severing mechanism and for subsequently displacing the holder which carries the severed terminal toward a bobbin for insertion of the held terminal into the bobbin.

Another object of the present invention is to provide an insertion machine which serially supplies a plurality of electrical terminals initially connected to a common carrier strip to an insertion station, wherein the insertion station includes a forming mechanism for bending the terminal to a desired configuration and a shearing mechanism which causes relative displacement of an individually formed terminal relative to the carrier strip to shear the terminal from the carrier strip and insert the terminal into a bobbin.

Other objects and many attendant advantages will become apparent upon perusal of the following detailed description taken in conjunction with the following drawings wherein:

With more particular reference to FIG. 1 of the drawings, there is illustrated in FIG. 1 a preferred embodiment of an insertion machine illustrated at l. The machine includes a framework 2 supporting an inclined table surface or easel'4 provided thereover with a cover 6 having an aperture opening 8 centrally thereof to expose a holding station generally illustrated at 10 for an operator of the machine 1 to locate a bobbin thereon of the type illustrated generally at 12 in FIG. 2.

With reference to FIG. 2, the bobbin 12, is generally of annular construction with a. central opening 14 adapted to encircle the rotor and windings of an electric motor (not shown) of any well-known type in the prior art. The annular bobbin 12' further is provided with a pair of generally opposed tubular portions 16 each having a longitudinal passageway 18 therethrough adapted for receiving corresponding motor brush 20 therein. The tubular portions further include respective pockets 22 which are open at one end 24 thereof to receive therein a generally U-shaped or channel shaped metallic electrical terminal 26. The machine according to the present invention is adapted to automatically sever each terminal 26 and subsequently insert the same into a corresponding pocket 22 in a manner to be described in detail; In use, each terminal 26 subsequently may be bent to overliethe end of a corresponding brush 20 to retain it in a corresponding tubular portion 16. A generally channel shaped tail portion 28 in the terminal 26 is adapted to be crimped onto an electrical input lead or wire (not shown).

The bobbin 12 is adpated to be provided on opposed sides thereof with L-shaped terminals 30 inserted into corresponding slots provided on the periphery of the bobbin 12. The tail portions 32 of the terminals 30 are generally channel shaped and are adapted to be crimped over input lead wires as well as the electrical windings of the motor which is adapted to be contained within the opening 14 of the bobbin 12.

It is an object of the present invention to provide a machine which inserts the terminals 26 and 30 into the bobbin 12 to provide a subassembly upon which further manufacturing operations may be performed, namely, assembling the bobbin 12 around an electric motor and with a central shaft 34 over which the bobbin 12 is assembled. The pocket portions 22 of the bobbin 12 are aligned with a pair of opposed elongated insertion stations generally illustrated at 36. The bobbin includes a pair of depending cylindrical portions 33 located beneath corresponding pocket portions.

With reference to FIG. 3 taken in conjunction with FIGS. 4, and 6, the details of an insertion station 36 will be described in detail. Each insertion station 36 is of similar construction and therefore only one will be described in detail for simplicity.

A corresponding cylindrical portion 33 of the bobbin is received into an aperture 37 of an anvil portion 38 of each inserter 36. The anvil portion 38 is stationarily mounted in any well-known manner to the easel 4 such that the cylindrical portion 33 of a bobbin will always be properly located at the work station of the machine As shown in FIG. 8 as well as FIGS. 4 through 6, the work station 36 includes a holder block 40, mounted on a base 41 which bears slidably along the anvil 38. The work station also includes a platen or shear block 42, with the face 44 of the shear block being vertically slidable along the face of the block 40 in a manner to be described in detail.

The holder block 40 is provided with a recessed channel 48 which communicates with one vertical surface 50 of the holder block 42. The channel has protruding thereinto a pair of spaced depending projections 52. The severing block 42 is provided with an integral horizontally projecting elongated arm 54. The arm 54'is provided with a chamfered edge 56 which is adjacent to a slotted portion 58 of the block 42. The slotted portion 58 therefore extends horizontally above the chamfered edge 56 of the arm 54 and into the shearing block 42. A second chamfered edge 60 is provided on the shearing block 42 adjacent to the slotted portion 58. As shown in FIG. 7, the chamfered edges 56 and 60 provide a flared opening communicating with the slotted portion 58. The work station 36 further includes a horizontal chute surface 62 over which a plurality of serially spaced terminals 26 may be slidably conveyed. More particularly, the terminals 26 are serially provided along a common carrier strip 64 such that the carrier strip 64 is received through the flared opening of the slotted portion 58 of the severing block 42, as shown more particularly in FIG. 8. Each terminal 26 is thereby serially conveyed along the chute surface 62 until a forwardmost terminal 26 is received into the channel portion 48 of the terminal holding block 40. The depending portions 52 of the holding block will then be located between the channel shaped portion of the terminal 26 and its corresponding tail portion 28. The forwardmost terminal 26 is thereby retained in the inverted channel 48 of the holder block 40 and is thereby held in position for insertion into the corresponding bobbin pocket 22.

As more particularly shown in FIGS. 4, 5 and 6, it is to be understood that the terminals 26 and the carrier strip 64 thereof may be conveyed along the chute 62 by any conventional advancing and indexing mechanism known in the prior art.

With reference to FIGS. 4, 5 and 6, further details of the insertion station will be described in detail. The severing bar 42 is illustrated as being secured to a cam follower housing 66 which is provided with an inverted recess 68 freely receiving therein an enlarged spherical ball bearing 70. The ball bearing 70 is only partially received into the opening 48, with the relative position of the ball bearing 70 within the opening 58 being determined by adjustment of an adjustment screw 72 which partially protrudes into the recess 68 for engagement upon the ball 70. The cam follower housing 66 is further provided with a recess 74 in the top portion thereof which receives the end of a coil spring 76 therein. The spring 76 is retained in compression between the bottom wall of the recess 74 and an overlying flange 78 which is fixedly secured to the machine 1 in any desired manner. As further shown in FIGS. 4, 5 and 6, the work station 36 further includes an elongated horizontal ram 80 slidably reciprocable in a channel defined between a pair of spaced plates 82 and 84. One end 86 of the ram 80 is connected to a pivot link 88 which, in turn, is operatively connected to a driving mechanism such as a relatively actuable power air cylinder (not shown) of any well known type'. The other end 90 of the cylinder is of relatively reduced thickness and provided with an inclined cam surface 92. The end 90 further is provided with an elongated recess 94 having a pin 96 transversely therein. A similar pin 98 is provided in an aperture 100 of the base portion 41 of the holding block 40. A coil spring 102 has its ends looped overthe pins 96 and 98 and is in constant tension while being disposed in the apertures 94 and 100. Initially as shown in FIG. 4, the ball 70 is received against the reduced thickness end 90 of the ram 80. When the machine is actuated, the ram 80 is slidably displaced'from right to left, causing the inclined cam surface 90 to be slidably displaced under the ball 70. The ball 70 is thereby forced to roll and thereby follow over the cam surface face 92. The ball 70 is thereby elevated to the greater thickness portion of the ram 80, thereby elevating the cam follower housing 66 and the severing block 42. Severing block 42 thereby is elevated or displaced vertically with respect to the terminal holding block 40 with the vertical face or surface 44 of the severing block 42 slidably displacing over the verticalface or surface 46 the holding block 40.

As particularly shown in FIGS, the carrier strip 64 which is disposed in the slotted position 58 of the severing block 42 also is elevated together with the severing block 42. Since the forwardmost terminal 26 is retained stationary within the cavity 48 of the terminal holding block 40, separation of the terminal strip 64 from the retained forwardmost terminal 26 is effected. Thus the carrier strip 64 when elevated as described, will be severed along a line defined at the intersection of the vertical surfaces 44 and 46. This separates the forwardmost terminal 26 from the carrier strip while it is retained within the holder block 40. The elevated cam follower housing 66 is elevated to compress resiliently the spring 76, the spring thereby urging the ball 70 in constant engagement over the surfaces of the ram 80. As shown in FIG. 8, when the severing block 42 is elevated, the horizontal arm 54 thereof will slidably traverse over the surface 50 of the terminal holding block 40 as shown in FIGS. 7 and 8. The arm 54 will thus be elevated in a position to cover the recess 48 to prevent the retained forwardmost terminal 26 from becoming misaligned within the recess 48 or from falling out of the recess 48 when it is severed from the carrier strip 64. As shown in FIG. 6, the ram is continued to be displaced from right to left, with the cam follower housing 66 retained in ite elevated position, and with the severing block 42 also retained in its elevated position.

Thus as shown in FIG. 6, as the ram 80 further displaces from right to left, the end thereof will engage against the base 41 of the terminal holding block 40, slidably displacing the base 41 along the member 38 over which it is slidably mounted. The holding block 40 and the base 41 thereof are thereby caused to be displaced from right to left, forcing the protruding tongue 27 of the terminal to be inserted into the pocket 22 of the bobbin. The block 40 is displaced from right to left as shown in FIG. 6 to such an extent that the channel 48 thereof is displaced beyond the arm 54 and thereby becomes uncovered from the horizontal arm 54.

The ram 80 subsequently may be retracted from left to right from its position shown in FIG. 6 to return all the described component parts of the insertion station 36 to their position as shown in FIG. 4. In doing so, however, the terminal 26 will remain inserted within the pocket 22 of the bobbin.

As shown in FIGS. 7 and 8, during displacement of the holder block 40 from right to left, the protruding portions 52 will engage against the channel shaped portion of the forwardmost terminal 26 forcing the terminal into insertion within the pocket 22. As shown in FIG. 7, the two protruding portions 52 are spaced apart a selected distance. The tail section 28 of the terminal 26 is of narrower configuration than the spacing between the two protruding portions 52. Thereby upon retraction of the rim 80, the holder block 40 will likewise be retracted into engagement against the vertical surface 44 of the severing block 42 without engagement on the tail portion 28. The coil spring 102 is maintained in constant resilient elongation to insure that the base 41 follows the ram 80 during retraction.

The preferred embodiment of the present invention further includes another pair of inserters illustrated in FIG. 3 generally at 104. The details of one of the inserters 104 will be described with reference to FIGS. 9 through 11. The inserter includes a pair of spaced blocks 106 and 108 which are secured in any wellknown manner on the surface of the easel 4. The plates define therebetween an elongated horizontal channel 110 in which there is slidably reciprocated a generally rectangular ram 112. The ram is driven by a powerair cylinder 114 having a linkage arm 116 pivotally connected to the ram 112 by a pocket and shaft assembly 120. The forwardmost portion of the ram 112 is recessed at 122 to provide a plate 124. A generally triangular plate 126 is rotatably mounted by a shaft 128 to the ram 112. The plate is provided with an inverted recess 130 receiving a coil spring 132 therein, with the ends of the spring 132 being retained between the plate 126 and the plate 122 of'the ram 112. The plate 126 further includes a projecting finger portion 134. The top surface 136 of the block 106 provides a feeding chute surface over which a carrier strip 138 may be slidably traversed. As shown the carrier strip 138 is provided with a plurality of spaced apertures 138 into which the finger 134 is selectively brought into registration. Upon slidable displacement of the ram 112 the finger 134 will thereby slidably advance the carrier strip 138 over the surface of the feeding chute surface 136. The terminals are serially spaced along the carrier strip 138 and are thereby slidably advanced together with the carrier strip upon slidable advancement of the plate 126. The plate 126 and ram 112 thereby provide a feeding mechanism for serially advancing the terminals 30 along the chute 136.

The forwardmost terminal is first advanced to a bending station more particularly illustrated in FIGS. 10 and 11. The block 106 is provided thereover with a cover block 138 having an inverted recess 140 therein. A narrow portion of the recess 140 receives the carrier strip 138 therethrough while a larger portion of the carrier strip receives the tail portion 32 of the terminal 30. The forwardmost terminal 30 thus is received under the block 138 and protrudes over a vertical channel 142 defined between a vertical surface 144 of the block 136 and a covering plate 146. A ram 148 is vertically reciprocated in the vertical channel 142. As shown in FIGS. 9 and 10, the ram 148 is connected by a pivot link 150 to a power air cylinder (not shown) whih is used to reciprocate the ram 148. As shown in FIG. 10, the vertical surface 144 of the block 136 is provided with a vertically extending longitudinal recess 148 the inverted bottom of which is provided with a threadedly adjustable set screw 150. As shown in FigS. 9 and 10, the uppermost end portion of the ram 148 is bifurcated at 152 to receive a generally elbow-shaped cam 154 pivotally connected by a pin 156 to the bifurcated portion 152 of the ram. One extended portion 160 of the elbowshaped cam 154 is traversable longitudinally within the recess 148 of the block 136.The other extended portion 162 of the ram is provided with a pair of spacd protruding arcuate cam projections 164 and is vertically traversable in impingement against the plate 146. As shown in FIG. 9, a forwardmost terminal is received over the channel 142, with the cam 154 initially recessed internally of the channel 142. With the terminal 30 thus retained over the channel and at least partially under the block 138, the ram 148 :is vertically actuated to propel the cam 154 to protrude outwardly of the channel 148, as shown in FIG. 10.. The arm 160 of the cam will stop against the set screw 150. The arcuate projections 164 will thereby engage the terminal 30 which protrudes from the block 138 and will thereby form the terminals 30 with a right angle bend as shown in FIG 10. The arm 162 will remain in impingement against the plate 142 to insure sufficient pressure against the terminal 30 to provide a forming and bending operation as illustrated. The end surface 166 of the block 138 is inclined so as to provide a slightly relieved space between the right angle bent terminal 30 and the block 138 to permit a slight bend in the terminal in excess of 90 to allow for resilient relaxation of the terminal after being formed or bent.

After the terminal is bent to a right angle position, the feeding mechanism is once again actuated to advance the bent terminal to an insertion and severing station illustrated more particularly in FIGS. 9 and 11. The insertion and severing station includes a vertical elongated channel 168 provided in the block 106 and the cover plate 146. As shown in FIG. 9, the block 134 is provided with an end plate vertically disposed at 170. A vertically reciprocating ram 172 is actuable within the channel 168. One end of the ram 172 is provided with a pivot connection 174. The other end of the ram is provided with a recessed portion 176 having a projecting platen or block 178 which protrudes above the end 177 of the ram 172. The end 177 of the ram is provided with a recess 180 in which there is received a spring loaded plunger 182. A lever arm 184 is rotatably mounted by a shaft 186 in pivotal relationship to a projecting flange 188 projecting fro the end 177 of the ram 172. The arm 184 is disposed to overlie the block 178, with the spring loaded plunger 182 urging the arm 184 to pivot in a counterclockwise fashion as shown in FIG. 9. When the feed mechanism as shown in FIG. 9, is actuated to advance the forwardmost right angle bent terminal 30, the terminal will be slidably received between the arm 184 and the block 178. More particularly, the arm 184 is chamfered at 190 to provide a funnel entry surface for allowing passage of the terminal 30 thereunder. As more particularly shown in FIG. 11, when the carrier strip is advanced, the forwardmost right angle terminal is forced to slide between the arm 184 and the block 178 and to be gripped therebetween by the counterclockwise urging'of the arm by the resilient plunger 182. As shown in FIG. 11, the arm 184 is provided with an inverted recess 192 which receives the tail portion 32 of the forwardmost right angle bent terminal 30 therein. Initially, the ram 172 is disposed in the inserting station 104 such that the block 178 thereof is in alignment with the chute surface 136 to allow for the carrier strip 138 to be advanced into overlying relationship on a falttened wall 194 provided by recessed portion 196 in the top end of the'block or plate 136. This is shown in FIG. 11. Also the cover plate 146 is provided with a recess 198 in the top portion thereof to provide a relieved groove receiving the tab 200 of the terminal 30 therein. The remaining portion of the terminal 30 around the tab 200 is received flush against the surface of the plate 146. As shown more particularly with reference to FIGS. 3, 9 and 11, the bobbin 12 is retained in position on the easel 4 such that terminal 30 may be driven upwardly by reciprocation of the ram 172 for insertion of the terminal 30 in the slotted portion of the periphery of the bobbin 12. More particularly, on upward reciprocation of the ram 172, the terminal 30 will be displaced upwardly as shown in FIGS. 9 and 11 while it is still retained gripped relation between the ram 184 and the block 178. As shown'in FIG. 11, the block 178 will traverse over the vertical surface of the block 106. Since the carrier strip 138 is captured in the recess 196 of the block 106, the vertical displacement of the block 178 will cause shearing along the carrier strip 138, allowing the sheared off or otherwise separated terminal 30 to be upwardly displaced independent of the carrier strip 138. Terminal 30 will thus be upwardly inserted into the periphery of the bobbin 12 with the tab 200 thereof latching in the bobbin 12, thereby retaining the terminal 30 secured to the bobbin 12. As shown in FIG. 9, the arm 184 is lifted above the block 170 as the terminal 30 is inserted into the bobbin 12. The end of the block 170 is provided with a chamfer 202. When the bobbin 12 is removed from the easel 4 together with the inserted terminal 30, the arm 184 will be forced to rotate clockwise as shown in FIG. 9 in opposition against the resilient spring plunger 182 thereby allowing removal of the terminal 30. The chamfer 202 thus provices a clearance permitting rotation of the arm 184 when in its elevated position shown. When the arm 172 is retraced to its initial position, the chamfered edge 202 will strike against the arm 184 as the arm is lowered together with the ram 172. This will cause the arm 184 to again rotate counterclockwise fashion such that is assumes its initial position overlying the block 178. In the meantime, during upward travel of the ram 172 the arm has a vertical surface 24 adjacent to the vertical surface of the block or plate which would impinge against the vertical surface to prevent clockwise rotation of the arm 194 until it is raised to its elevated position, further insuring that the arm is retained over the terminal 30 during upward travel thereof for insertion into the bobbin 12.

Actuation of the various insertion stations may be timed in a desired sequence such that the terminals 30 and 26 are inserted substantially simultaneously. This will enable eachbobbin 12 to be placed into position on the easel by an operator and then removed after all the terminals 26 and 32 are inserted, to result in a machine and method for inserting terminals into a bobbin and to provide for a bobbin subassembly having terminals assembled thereto.
